We’re looking for a Senior AI Software Engineer with strong Python and AWS experience who enjoys taking ownership and shipping products end-to-end. You’ll work primarily with Python, FastAPI, GenAI and AWS , building scalable backend services, AI-powered features and data pipelines. You'll make real architectural decisions, like knowing when an LLM beats a well-tuned ML model or a simple heuristic, and own features from idea through production. We move fast, keep things pragmatic and give engineers a lot of ownership.

Develop scalable backend services with Python & FastAPI.
Design, deploy and operate production systems on AWS.
Drive architecture and technical decisions and contribute to code reviews.
Build practical GenAI solutions and evaluate where LLMs actually add value.
Use AI coding tools such as Claude or Codex to improve development workflows.
Own reliability, observability and performance of what you build.
Requirements
Senior-level Software Engineering experience with a strong track record of shipping production software.
Practical experience with GenAI and AI-assisted development.
Experience in a startup, scale-up or similarly fast-moving environment.
Strong end-to-end ownership: you take problems from architecture → code → deployment → production.
Strong communication skills and the ability to make independent technical decisions.
Strong Python skills — Python is central to this role.
Hands-on AWS experience or similar cloud provider — this is essential.
Experience with FastAPI, cloud architecture and production systems.
